pic: 4 inch 3D printed wheel

[steelerborn]

The wheel is ABS plastic.
It is really light at .105 pounds (according to Creo 2 and Solidworks 2012 Premium), this wheel was mainly to show off the 3D printing ability that we have now.

It is much stronger than I anticipated it would be, but I doubt we will use it on a bot. The thing is I added a couple of things to this wheel that is not possible on a lathe and mill, to show the kids how cool 3D printing is.

This wheel is about 1/4 of the weight of its AM equivalent. I have another style that is a bit beefier and is about 1/2 the weight of the AM equivalent. But I don't see a problem throwing some tread on this thing and giving it to the kids to try out. If it holds up then I will be very impressed.
